To all whom it may concern:

Be it known that I, SAMUEL McIIiiivRY,

- a citizen of the United States, residing at Bloomsburg, in the county of Columbia and State of Pennsylvania,;have invented cer-' tain new and useful Improvements in Broom-Manufacturing Machines; and I. do

declare the following to be a full, clear, ex

act description of the'invention, such as will enable others skilled in' the art to which it appertains tomake and use the same,-refer-.

ence being had to the accompanying drawings, andto the letters and figures of reference marked thereon, which form apart of thisspecification, a

This invention relates to improvements in machines for manufacturing. or; making brooms. I *The invention has for its object, among other things, to J-provide for readily. and

firmly holding the broom-forming material during the processof manufacture. M

A further object of the-invention isto pro-- forming-a vide for rapidly and effectively desirable and substa'ntial broom. I

A still further object of the invention is to provided for adapting the machine for ready adjustment for making brooms of various sizes;

With-these and other objects in View, the invention consists of certain instrumentali detailed construction and arrangement} of parts maybe made without departing from the spirit or scope of the claims and in which drawings Figure 1 is a plan View ofmyinve'ntion,

the same being in inoperative positon.

' Fig, 2 is-a sectional elevation thereof taken on line 22 of Fig; 1, with oneof the brushblock holding members or jaws also shown in dottedjline position, togetherjwith said brush-block and I broom I'naterial'looping member, as when securingthe brush-mate rial to said block or broom-head.

J Fig. 3 is a horizontal detailed sectional view 'ofthe complete article or broom.

broom-material looping member is initially disposed for looping said broom-material.

Fig. 5 is also a like sectional view of the same parts, as when the broom-material looping operation has been effected and before thefboxing, as it were, of said broommaterial uponthe block orbroom-head has been, and is about ready to be performed.

Fig, 6 isa' transverse vertical section taken through Fig.15, .on line 66.

In carrying out my invention, I suitably mount the several operative parts thereof upon ,a generalframe' 1. Alining shafts 2,- 2, having their opposed ends suitably spaced apart for a purpose presently seen, are equipped at: said ends with jaws 4 and 5, respectively, of preferably oblong or rectangular form,lone having a recessed face, said jaws being adapted'toreceive therebetween, and provide for the holding of the broommaterial holding blockor head 24:. Oneof these shafts 2 has suitably secured thereon a blockor bracket 8, a short distance from its jaw-equipped end,which serves for temporarily holding what may be termed a looping device 9, the operation and function of which will'later be explained. A gage 7, of suitable adaptation for use in regulating or truing the lengths of the strands of the broom-material, is suitably secured upon the same shaft'2.

Upon one end of the shaft is freely mounted a preferably U-shaped plate or yoke13, it being let into' anannular reduction of said shaft and held in place by a nut appliedto saidend of the shaft. Fulcrumed upon the supporting frame and having its, lower'end pivoted to the yoke or plate 13 is' a weighted lever 10, for bringing the brushmaterial holding'block-jaws4, 5 together or rather in engagement with said block. The weighting of said lever is effected preferably by suspending therefrom a Weight. 12 by means of ac'hain 11 with itsend's secured to said lever and weight, respectively, with the chain initially resting upon the lever, the weight, however, freely depending therefrom, as shown, thus providing for the re tention'of th'e lever'ineither of its positions under pressure oragainst casual movement, as is obvious. i j

Two clamping members *14 and 15 are oppositely positioned to each other, above and below the broom-materialholding block within its engaging jaws, respectively, each 7 chains 19 to the-supporting frame and pref- 1 being preferably of bail-li-ke fornnwith its arms suitably pivoted to preferably up-. wardly and downwardly progecting .PO-I'lllOIlS of the supporting frame'at' their extreme rear ends.

and the levers 16 and 17 are pivotally connected by links 22 and 23 to an upright 21 secured to a transverse beam 6; said levers 16 and 17 are also connected preferably by tain the levers 16 and 17 in effective position when said levers pass forwardly ofthe perpendicular, particularly as seen in Flg. 4.

Pairs of rods or members are carried by the beam 6 and'have connected'the'reto an operating bail-like lever 29, in turn linked as at 30 .to supports 31 suitably secured in position, all as seen particularly in Fig. 1. These rods or members 20 are provided at thei rforward ends, in the upper surfaces, with notches or recesses to receive the brush material-looping devices 9, the 1atter,however, as previously stated, being temporarily disposed upon the block or bracket 8 on the shaft 2;, .7 until called for in effecting the looping operation.

I -When thejaws 4,. .5 have been moved sow as tougrip, or, clamp thefbroom-material holding-block 24in position, as seen in Figs. 4 and 5,,which is effected by moving the lever-lOinto the dotted line position, indicated in Fig, 2, (the broom-material having been suitably gaged and placed upon said block) the lever 29 is suitably actuated or moved into the position indicated in Fig. 5. The looping device'9, itwi-ll be seen, willhave engaged and looped ordoubled the broommaterial strands upon themselves, this also being disclosed by Fig.6. The looping device 9,is now Withdrawn and again disposed uponthe block 8, and by suitably manipulating-thelever29, the clamping members 14 and 15 are brought in clamped positionupon the broom-material as seen in Fig. 4, for tightly or .firmly holding the broom material npon the block. 24,,the clamping members 14, 15? being thus retained until the broom materialhas been wired as at 26 down 1 uponjthe block and a metallic cap 28' has been suitably v nailed or secured over the looped and wired end of the broom material, as by stapling as at 27 all as shown particularly ,inFig. 3. *Now by suitably actuating the lever 29 the clamping members 14, 15 are withdrawn, and by suitably actuating the lever-10 the block-clamping jaws 4, 5 are released from saidblo'ck, permitting the resultant broom-forming member, with its attached head, to be removed. ,It will Said clamping members; 14, 15 v are pivotally connected to levers 16 and 17,.

be noted that the lower clamping member 15 has an approximately U form, the lateral upwardly extendingportions thereof serving, as previously indicated, to effect the boxing as it; were, of the broom material a and thus .in place.

provide for compactly holding it In operation, the broom material, Q nated as '25, is applied to extend longitudinally along opposite surfaces of the head or tively engage and hold thebroom' materialf uponthe block 24, the membersor arms 20 being carried slmultaneouslyin thesame d1- motion as the-members14, 15 and positioned as 1n's'a1d'figureJ The broom materialisnow wired down, as at 26, upon the block24, and staples driven through=-the :wire into said block. The lever 10. is next moved into the .dottedline position, asin Fig. 2, providing for carrying the head 8, with the loop 9, into the dotted line position of saidfigur'e,

whereby the shaft 2 willzbe longitudinally" moved, providing for clamping the block or head 24 between the jaws 4 and 5, ancl'soactuating the member-9 as tocause it'to' fold the: brushmaterialflupon itself, as seen in Figs. 5 and 6, the lever'29 havingbeen previously moved into initial position as indicated in thesaine figure and Fig. 2; Siinul taneously with this latter manipulation of parts, as in the movement'ofthe lever 10', the member '9will be moved into locked engagement with the arms'ofthe member20, asseen in Fig; 6, providing for the holdingof the broom material .in position for the application thereto of the cap 28."-- Preliminary, however, to applying the cap, the. lever 10 is moved into initial orfull-line position;

asseen-in Fig; 2, taking the jaw4-and the member =8, ;,Wll3l1 the looping; member .9 removed to thelatter, out of the way for'the application ofthe cap. Thelatter is now suitably secured over the inner or butt'end of the broom, thus far completedfby suitably nailing it to the headorbl'ock24, thus. co1npleting 'the' brush forming -operation.. .It will be understood that' in nailingithe cap and wiring the broom material up onthe head or block 24 the shaft 2. is capable ofbeing readily turned .or v revolved manually/forconveniently performing, said nailing and wiring operations.
